UNITE STATES PATENT OFFICE GEORGE H. ANGERT, OF CINCINNATI, OI-IIO, ASSIGNOR TO ANGERT BROTHERS, A PARTNERSHIP COMPOSED F ARTHUR C. ANGERT AND GEORGE H. ANGERT, OF

CINCINNATI, OHIO ADJUSTABLE TABLE Application led August 31, 1923.

My invention relates to tables, and to articles of furniture to have tops convertible from one size to another.

The specific object of my invention is to provide a table, usually a kitchen table which is convertible from normal size porcelain top table, to a double size wooden table7 without removal or addition of parts. I have found that by a simple geometrical calculation, I 10 can provide a table which is in two sections hinged at the middle, and adapted to fold on each other, the one section being pivoted to the table so that it will rotate around from position to cover the entire frame, to position at right angles, to cover half of the frame. Then on the lower face of the hinged half7 so ar ranged as to be exposed when folded over the pivoted half, I mount a porcelain cover.

I accomplish my object by that certain arrangement of parts to be hereinafter more speciflcally pointed out and claimed.

In the drawings Figure l is a plan view illustrating the table and the means for calculating the pivotal position of the one section of the top.

Figure 2 is an end elevation of the table when converted into a porcelain top.

Figure 3 is a perspective of the table when used with the porcelain top.

Figure 4 is a perspective showing the partial operation of unfolding the top.

Figure 5 is a perspective view of the table showing the top in its double area, and located in position. i

In proceeding to make up my table, I first determine upon the size desired for the porcelain top, and for the double area when unfolded, which will be twice the area of the porcelain top. I then lay out on a drawing, the size of the porcelain top as illustrated at w, 1 .e (Figure l). I then take the median line of the said view and at right angles thereto, I draw in a figure which represents the top turned at right angle. rihis is shown in the figure o, b, c, (Z. I may then finish out the area of the double top by drawing in the folding half as shown at 0, d, e, From point c I draw an arc7 and from the nearest corner LU I draw an are of equal radius, `With the two intersections of these arcs as points I Serial No. 660,311.

draw a line m. I then draw an arc from point a, and an arc from point x of equal radius, and from the two intersections of these arcs, I draw a straight line a. IVhere lines n and m intersect at the point p on the table frame is the pivot point for the pivoted portion of the table top. The other portion of the top is then made of equal size thereto and hinged to its long edge.

When so constructed it is evident that upon swinging the rectangle w, y, e, around to position a, Z), c, d, the line fw, e, will lie along the middle of the space formerly occupied by the rectangle w, y, e.

Referring now to the table itself, I have indicated legs l, frame boards 2, and a cross board 3 for the pivot of the one section. The one half section that is pivoted is marked as 4, and the pivot may be formed of a screw bolt 4a set through the board 3, and screwed into the base of the table section 4. The pivot point will be located as described by the layout of Figure l and the frame built accordingly.

The section 5 of the table is hinged to the section 4 along one of its long edges, by means of hinges 6. As this section is to be on top when the table is folded up, I finish the bottom of the section 5 with the desired finish. IVhile I have termed` the top a porcelain top, I do not wish to be understood as limiting myself to any particular kind of finish, but only7 as bringing out the fact that a special finish can be provided which is different from the rest of the table. without detracting from the appearance of the table when unfolded, since this finish can be placed on what is the underside of the folding section.

In Figure 3 the table is shown folded up. In Figure 4 the operator has started to fold up the section 5 and to swing the section 4 on its pivot. In Figure 5 the swinging has been completed, and the double top is open and down on the frame.

In forming a porcelain finish, I find it convenient to obtain the porcelain in the shape of a plate having a flange 5a, which is screwed as at 5b to a wooden filler 5. The filler will be in the form of a matching top to the section 4, to give a neat job.

It is evident that my invention is specially advantageous in a kitchen Where a porcelain top is often desirable7 and the expense of a large top makes it Within range of all users to have ene of my tables 'for Working on the porcelain top, and still unfold it to larger size Where needed as a service table or a table from which to eat.

Having thus described my invention, what I claim as nf-W and desire to secure by Letters Patent, is 2- l. In a. table the combination with a traine of a table top section adapted in one position to cover the traine, and having a pivot to said frame, said pivot being so located that the said top section can swing to a position at right angles to its first noted position in which case it will cover hut one half of the frame,anda secondtcp section of equal size to that iii-st mentioned and hinged thereto along one side, said hinge being arranged so that when in the second position of the irst section above described the second section Will told to a position to cover the remaining halt of the table, and when folded up, said second section will lie over and cover the first noted section, said second section having` a porcelain cover thereon comprising` a flanged metal plate set over the bottom of the second section, With the flanges embracing the edges of said section and secured thereto, the porcelain inish of which Will be uppermost when 'folded over the top et the first section noted, the opposite side of the second section being of the saine `iinish as the top ot' the first section.

2. In a table, a leg supported frame7 a 4first top sectionpivotally connected to said trarne for swinging movement in a horizontal plane, to permit said section to he moved from a position covering the frame to a position covering substantially only half o'l the trame, a second top section equal in size to the first section7 and having one of its side edges hinged to one side edge of the iirst top section to permit the second section to be superposed on the 'irst section to form al kitchen table, or to lie along side the iirst section to :form a dining table, and a porcelain finished unobstructed metal cover on one side of the second section, and adapted to torni the upper surface of the table top when the second section is superposed on the first section, the opposite side ot the second section being oit the saine nature and linish as the upper surtace of the iirst section, the metal cover adding suliicient Weight to the secc-nd top sect-ion to hold beth sections in either of their positions.
